Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stadium that is also used as a velodrome, and more specifically, the present invention relates to a stadium that can be used in conjunction with a velodrome, and more specifically, it is possible to change the stadium inside the stadium from one type of use to another, that is, from a baseball field etc. to a velodrome, and from a velodrome to a velodrome. This relates to a stadium that can be converted into a baseball field or the like.

If stadiums for commercial purposes such as baseball stadiums are used as exclusive stadiums, they will not be used to their full potential throughout the year due to the off-season, etc., and will have to remain idle for a considerable period of time. is the actual situation. There is no need to explain the waste of vast amounts of land and facilities for this purpose. On the other hand, the velodrome, which is a special facility, has been forced into a similar idle period, and because there is a special facility called a track, it cannot be used for other sports, and it is also impossible to use other stadiums to hold events. It was hot. Moreover, since there is a lag between the timing of keirin and other sports, if this can be used in conjunction with this, it will be possible to utilize the facilities extremely efficiently.

In view of the above, the present invention enables stadiums such as baseball stadiums to be used in combination with bicycle velodromes. Hereinafter, an embodiment of a stadium used as a velodrome according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a stadium for baseball, etc., where the stand building is approximately rectangular in plan and each corner is cut into squares and curved, and has spectator seats 3 around an inner stadium 2. Assuming that the size of the stadium is 128.5m in length and width and 150m in diagonal length, the pitch line for the baseball field is 99.5m,
It has an ideal shape with a center line of 123m and a keirin track of 4.00m.

The bleachers 3 are divided into a fixed stand 4 and a movable stand 5, and one of the movable stands 5 has a curved bleacher section 6.
A fixed track for bicycle racing 11 provided on the inside of 6′,
The guide rails 7, 7 are configured as a movable stand with a base divided radially against the curve on the guide rail 7 on the guide rail 11', and the guide rails 7, 7 are provided on the back side of the fixed runways 11, 11' on the spectator seat side and on the stadium side. ′ to be able to move laterally. The spectator seats 3 of the fixed stand 4 and the movable stand 5 are both formed in the shape of steps. The movable stand 5 is provided with stacking rails 5' and 5'' on the upper and lower edges, and furthermore, a storage chamber 8 is constructed underground in the center of the movable stand, and a lifting lift 9 is installed inside the storage chamber 8. The movable stands 5 are sequentially mounted and stored.In other words, the lower part of the center of the movable stand 5 is the lifting lift 9 and the storage chamber 8 that stores it. 5, 5 are loaded one after another and the lift 9 is housed in the chamber 8, the insertion/ejection passage 13 is inserted into the cutout portion to complete the passage.Insertion/ejection passage 1
3 has a built-in drive motor in the front part and is equipped with moving rails 15' and wheels 14' to enable automatic travel. The elevating lift 9 is lowered each time the movable stand 5 is mounted by an appropriate means such as hydraulic pressure. It goes without saying that the movable stand may be handled in other ways, such as a sliding type or a transport type.

In the stadium 1, running paths 10 are arranged diagonally when used as a velodrome.
The fixed tracks 11 and 11' forming the relatively curved part are fixedly installed at the lower part of the movable stand 5, and the movable tracks 12 and 12' forming the straight part are each divided and one end of each is fixed to the lower part of the fixed stand 4. It is rotatably moved around the shaft 16 by bearing on a shaft 16 installed on the side, and can be stored in the lower part of the fixed stand 4 when not in use. Movable track 12,1 of the track 10
A flexible vehicle 14 is provided at the bottom of each of the stadiums 2', and is mounted on a rail 15 installed in the stadium 2 so as to rotate. Although the track rotation means in this case is automatic, it may be towed by a tractor or the like. Of course, this can be carried out without covering the dissociated track by using a movable stand or the like. The running path 10 is constructed so that the slope increases as it approaches a corner. In the case of a baseball field, fixed stands 4 are installed as shown in Figure 1.
The ground is constructed with the home plate located at the center of the seat A. As is clear from the above configuration, when the present invention is used as a baseball field or the like, the running path 10 of the velodrome is equipped with fixed stands 4.
The movable stand is stored at the bottom of the movable stand 5, and when converting to a velodrome, the movable stand is moved and mounted on the lifting lift 9 in the storage room 8, and then moved to the storage room 8.
The movable tracks 12 and 12' of the track 10 stored in the lower part of the fixed stand 4 are connected and arranged by rotating on the rail 15 about the shaft 16, and the fixed tracks 11 and 11 are ′ so that it can move and run continuously.

As described above, the present invention constructs a stadium by arranging spectator seats consisting of fixed stands and movable stands in a substantially rectangular shape around the stadium 2. By arranging the running track of the velodrome in the same direction, and by arranging a movable track and a fixed track at the bottom of the fixed stand 4 and the movable stand 5, respectively, to enable joining and disassembly, it is impossible to use them together in the past. This allows the velodrome, which has traditionally been used as a velodrome, to be attached to another stadium. In addition, the layout can be changed almost automatically and quickly without the large amount of labor and expense required in the past, and the appearance is similar to that of a dedicated stadium due to the use of movable stands. can be maintained, and space wastage can be kept to a minimum.
